Why can't I plug in both the ground and power in my amp?

[rodneydude23 5]

So I plug in the ground and it fine. Then I plug in the power and it starts to fry. The same thing happens in vise versa.

What could becausing this?

He has a 99 camry, his amp is a Hifonics Titan 750.2.

you say starts to fry... you mean like magic blue smoke? a funny smell, a couple of sparks? are there on-board fuses? maybe an internal short? do you have some pics of the guts? a video?

also is the remote wire plugged in while you are putting in ether the ground or power

Yeah all that. I'm thinking internal short. The car reeks.

It sounds to me like you have the polarity reversed.

ouch!

so have you guys looked into taking off the back of the amp and see if something looks burn/dead?

If so, that amp ain't gonna be very happy.

Is your ground disconnected form the battery?

Post some pics of whats happening and im sure someone can guide you in the right direction..

Open up the amp and check anything inside.

Mosfets,caps,Etc

Something similar happens to a friend's amp

Plugs in power and a transformer/transistor (forgot the name) starts heating up and smoking. Some of the mosfets were bad.

Either the polarity is wrong or the amp has a fried power supply

Sounds like it is broke. What brand is it? I see it is a hifonics not sure if db-r works on those.

I understand what you are saying.. I think

When you put the positive in you hear a pop coming from the terminal? Or inside the amp? Does it sound like when you plug an appliance in at home and hear the pop of the leads making contact?

That's normal... Ground should always go first when putting in, and + should always be taken out first when taking it out.

Actually you do ground last because there is no current flow without ground so you cant accidently f up anything.

Some amplifiers can be grounded through the frame of the amp and burn up.

Good point I'm a auto tech so I think like one but I will remember that
